Based on visual observations from HVO and National Park Service (NPS) crews and web camera views, HVO reported that during 30 April-6 May lava flowed SE through a lava tube system underneath Kilauea’s Thanksgiving Eve Breakout (TEB) and rootless shield complex to the Waikupanaha ocean entry. On 4 May, lava flows from breakouts on the pali reached the coastal plain. Kilauea summit earthquakes were located beneath the Halema’uma’u crater, along the S-flank faults, and along the SW and E rift zones. The eruption from the vent in Halema’uma’u Crater continued to produce white plumes with minor ash content that drifted mainly SW. During most nights incandescence was seen at the base of the plume. Seismic tremor was elevated. The sulfur dioxide emission rate was high and fluctuated between 540 and 1,250 tonnes per day during 30 April-5 May. The background rate was 150-200 tonnes per day.
